IMPROVEMENT IN MACHINES FUR CUTTING, PUNCHING, AND UPSETTING TIRES.

Specification forming'part of Letters Patent No. 117,116, dated July 18, 1871.

To all whom t may concern:

Beit known that I, HIRAM B. Snvnv, of Vienna, in the county of Kennebec and State of Maine, have invented a new and useful Improved Ma` chine for Punching, C utting, and Upsettin g Tires 5 and I do hereby declare the following to be a full, clear, and exact description thereof, suliicient to enable others skilled in the art to which my invention appertains to fully understand, make, and use the same, reference being had to the accompanying drawing making part of this specification, in which- Figure l is a side elevation of my machine mth a portion broken away to show the construction. Fig. 2 is a view of part of the same, showing a cross-section on ythe line .r x of Fig. l.

Like letters ofreferenceindicate corresponding parts in both of the gures.

rlhe subject of this invention is a machine for punching, cutting, and upsetting tires, Ste.; and it consists of the combination and arrangement of parts hereinafter described and claimed.

A may designate the bed and B a standard,

. cast in one piece, upon which the punching, cutting, and upsetting mechanisms are arranged. The punching mechanism consists ofthe punch a secured to or made with the carrier c, which is secured in and passes through the openings or bearings made in the recessed head D and aprojection, b, of the standard B. A coiled spring, c, resting' on the projection b, surrounds the carrier for a suitable distance, and is held inl place thereon by a pin or /other device. rI he carrier, also, is provided with a head-plate, (l, which is situated within the recessed head D, and aga-inst which the operating-cam bears. A removable plate, F, having' an opening through its center for the passage of the punch, is secured in a recess in the bed A made for that purpose, and an opening underneath the opening in plate F is made through the bed A for the passage of the pieces punched out of the tire, or whatever is being perforated. The plate F is secured in the recess in the bed by means of one or more wedges, l l. A spring-punch or countersi11k,E,is secured in lugs projecting' from the side ofthe standard, and is provided with a rest or table, c, also projecting from the standard underneath the countersink. rlhe cutting mechanism consists of a stationary blade, f, bolted or otherwise secured to a flange, G, cast with the bed A; and a blade,

h, secured to a heavy lever ,gr jaw, H, hinged between two ianges, I, on the bed. The blades f and h, punch a, spring c, and plate F, and the colmtersink E, should be made of steel to insure strength and perfect cuttin g-edges. The upsetting mechanism consists of av serrated cam, t', secured to a iiange projecting from the bed, and is provided with an operating-handle and a serrated bed, j, made opposite the cam on the bed A, between which and the cam one part of the tire is held, while the other part is held between a similar cam, i', and bed j, the former of which is secured to, and the latter made with, a removable casting, J, attached to the carrier C.

The several parts are operated by the means and in the manner now to be described.

A lever, K, forked at one end, is secured on the pivot on which the jaw H is hinged. A cam-lever, M, is hinged in the recessed head D over the plate d, and is connected by one or more links, L, to the lower part of the lever k, and a pitman, N, connects the head (l oi' the carrier and one end of the lever H. The lever K and link or links L are provided with a number of holes through them, by means of which the several devices can be adjusted to conform to the size of the article being worked. By pulling the lever K down the link L draws the cam-lever M also down, and it presses against the plate d, whereby the punch is operated, and by means of the pitman N the upper blade of the shears is also pressed downward so as to cut whatever may be placed between the blades, the spring c forcing the parts back to their normal position after each stroke. As will be seen, if a tire which is to be upset be secured properly between the two cams and the serrated beds when the punch is forced down, the castingl J, being secured tothe punch-carrier, will also descend with it and thus quickly upset the tire. The countersinkin g ofthe bolt-holes in tires, Sto., can be readily accomplished by means of the countersink E. rIhus constructethpthe machine may be seciued to the bench or elsewhere bymeans of screws, bolts, &c., passing' through flanges on the bed. As is obvious, any desired size and shape of punch mayjbe used, and, of course, a plate, F, of corresponding size and shape, will also have to be inserted in the recess in the bed A. Vhen not in use the casting J .may be detached from the carrier, an d so,also, if the shears be not wanted, the pitman N may be detached.

The utility, convenience, and compactness of a machine combining the devices shown in mine Will readily show its great value to the blacksmith and carriage-buil der especially, and, as will appear, it can be produced at a cost much less than the aggregate of each machine separately, besides being more readily manipulated and occupyin g much less space in the Workshop.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is-
